Abstract
This present invention is a device having a mechanical bearing formed by two coaxial rings, one fixed relative to the machine and the other rotating, between which at least one rolling element is moveably positioned, at least one non-conducting positioning arrangements secured to the fixed bearing ring, the positioning arrangements including at least one placement holder for at least one conducting element forming a first plate of a capacitor, at a distance from a conducting part of the rotating ring forming the second plate of the capacitor, and with the positioning arrangements attached to at least one partitioning arrangements, the partitioning arrangements being used to create a space between the two plates, thus forming a dielectric insulating medium, and to act as a sealed enclosure for this insulating medium by being in contact with a part of the surface of the rotating ring.
